Hardware accelerators are scored according to various metrics and attributes that characterize the accelerators. Examples of suitable accelerator scoring criteria include whether the software simulation of the accelerator is complete, whether hardware testing is complete, whether the accelerator is currently deployed, the number of times the accelerator has been deployed to a private cloud, the number of times the accelerator has been deployed to a public cloud, ratings by users, number of failures, number of executions, space utilization and efficiency, code metrics, power consumption, speed, and image characteristics, including space used, resources used, use of dedicated functions on a programmable device, etc. These accelerator scoring criteria are tracked for each accelerator in an accelerator scoring catalog. When an accelerator is needed, accelerator selection criteria is specified and compared with the accelerator scoring criteria in the accelerator scoring catalog to locate one or more accelerators that satisfy the accelerator selection criteria.
